AFNetworking在3.0版本中删除了基于 NSURLConnection API的所有支持。AFHTTPRequestOperationManager已经抛弃,所以需要对数据请求进行改动。
Get请求
//使用代码
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager GET:url parameters:nil success:^(NSURLSessionDataTask *task, id responseObject) {
//成功
NSDictionary *obj = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:nil];
} failure:^(NSURLSessionDataTask *task, NSError *error) {
//失败
}];
AFN2.0:
NSURL *URL = [NSURL URLWithString:@""];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
op.responseSerializer = [AFJSONResponseSerializer serializer];
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
[[NSOperationQueue mainQueue] addOperation:op];
NSURL *URL = [NSURL URLWithString:@""];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
